Description

Technical Field

[0001] This invention relates to an electrical testing device and its usage method based on a multi-rotor unmanned aerial vehicle (UAV) platform. Background Technology

[0002] With the gradual deterioration of the operation and maintenance environment for transmission lines, the number of lines requiring power outages for technical upgrades is increasing. Before any maintenance work begins, personnel must perform voltage testing on the affected lines. This is the first step in the maintenance work and a crucial step concerning the personal safety of the workers. Traditional voltage testing involves workers wearing protective suits and carrying voltage testing equipment climbing the tower. Maintaining a sufficient safety distance, they wear insulated gloves and use a telescopic contact voltage detector to perform contact voltage testing on the line. The sound and light signals from the detector determine whether the line is energized. This process is time-consuming to climb the tower, physically demanding, involves cumbersome procedures, and carries risks such as falls from heights, being struck by objects, and electric shock.

[0003] Existing document CN213633592U discloses a voltage detector for AC power transmission and distribution lines, comprising a voltage detector body, a rubber handle at one end of the voltage detector body, an anti-static layer on the outer surface of the rubber handle, a voltage detection telescopic rod on one side of the rubber handle, and a voltage detection head on one side of the voltage detection telescopic rod.

[0004] Existing document CN2781387 describes a full-loop self-testing AC high-voltage detector. Existing AC high-voltage detectors have DC self-testing circuits with incomplete testing capabilities. The main feature of this invention is that the self-testing circuit of the full-loop self-testing AC high-voltage detector, composed of an audio-visual display and a multi-section telescopic operating rod, uses an AC self-testing circuit that generates a 50Hz square wave AC small signal to simulate AC high voltage. The self-testing circuit consists of R1, R2, R3, R4, R5, R6, Q1, Q2, C1, C2, C3, D1, D2, D3, U1, and U2. The output terminal A of the self-testing circuit is also electrically connected to the lower end of the probe on the audio-visual display of the AC high-voltage detector. This invention provides a safe and reliable full-loop self-testing AC high-voltage detector.

[0005] Neither of these two methods can avoid working at heights, which carries a certain degree of danger. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a relatively safe voltage testing device and its usage method based on a multi-rotor unmanned aerial vehicle platform.

[0007] The present invention adopts the following technical solution:

[0013] An electrical testing device based on a multi-rotor unmanned aerial vehicle platform, wherein the suspension device further includes a wire hanging device, the wire hanging device including a rotating hole on a connector, a main arm with one end located in the rotating hole and rotatably connected to the side wall of the rotating hole, a rotating arm at the other end of the main arm, a bolt embedded in the main arm and located in the inner cavity, an annular snap-fit ​​groove on a positioning member, and an upper limit platform for limiting the edge of the positioning member, wherein the rotating hole communicates with the inner cavity and the outside.

[0014] An electrical testing device based on a multi-rotor unmanned aerial vehicle (UAV) platform includes a suspension device further comprising a spring-loaded mechanism disposed between a main arm and a rotating arm. The spring-loaded mechanism includes a spring-loaded arm disposed on the main arm and near the rotating arm, a hanging hole disposed on the main arm and near the rotating arm, a rotating hole disposed on the main arm and near the rotating arm, a spring-loaded hole disposed on the rotating arm near the main arm, and springs A and B disposed within the spring-loaded hole. The rotating arm, hanging hole, and rotating hole are all located below the spring-loaded arm. The rotating hole is located to the lower right of the hanging hole. One end of spring A is inserted into the hanging hole, and the other end of spring A is fixedly connected to one end of spring B. The other end of spring B is fixedly connected to the bottom of the spring-loaded hole. A notch is provided on the side of the rotating arm near the main arm, and the notch is inserted below the spring-loaded arm. The rotating arm and the rotating hole are connected by a pin.

[0015] An electrical testing device based on a multi-rotor unmanned aerial vehicle platform, wherein the wire hanging device and the return device are in one-to-one correspondence, and there are three sets of each wire hanging device and the return device.

[0016] An electrical testing device based on a multi-rotor unmanned aerial vehicle platform, wherein spring A and spring B are both tension springs, and the diameter of the lower end of the safety buckle is less than or equal to the diameter of the through hole.

[0017] A method for using an electrical testing device based on a multi-rotor unmanned aerial vehicle (UAV) platform includes the following steps:

[0018] S1. Press the safety buckle on the ground to open the main boom and rotating boom, so that the bolts are engaged in the annular locking groove, and ensure the stability of the three sets of main booms and rotating booms;

[0019] S2. Test the power frequency signal generator and multi-rotor UAV on the ground using a controller;

[0022] S5. Increase the altitude of the multi-rotor drone to move the device away from the wire, and then control the multi-rotor drone to land smoothly.

[0023] The positive effects of this invention are as follows:

[0024] In this invention, when the safety buckle is pressed, it causes the positioning component to move downwards. At this time, rotating the main arm engages the bolt in the annular locking groove. When the positioning component is lifted using a multi-rotor drone and a lifting ring, the bolt is locked in the annular locking groove. After the inspection is completed, pressing the safety buckle again and rotating the main arm disengages the bolt from the annular locking groove, allowing the main arm to rotate until it contacts the carbon nanotube for easy storage and placement.

[0025] When the rotating arm collides with an obstacle, springs A and B in the rebound device can provide elastic force to the rotating arm, causing the rotating arm and the main arm to bend relative to each other and return to the state where the rotating arm presses against the rebound arm.

[0026] In addition, this invention:

[0027] 1) It eliminates the need for manual climbing of the tower and carrying heavy tools, thus preventing falls from heights.

[0028] 2) Using this invention can avoid the risk of electric shock that may occur when personnel climb the tower to directly test for electricity.

[0029] 3) The controller can be a handheld terminal. Using this invention, the voltage detection results can be fed back to the handheld terminal in real time, thereby solving the problem that ground personnel cannot accurately receive the sound and light signals when the overhead wires are too high.

[0030] 4) It can effectively reduce the labor intensity of operators, ensure personnel safety, and improve the efficiency of voltage testing. Attached Figure Description

[0058] Example 3

[0059] As attached Figure 1 As shown in Figure 6, based on Embodiments 1 and 2, a method for using an electrical testing device based on a multi-rotor unmanned aerial vehicle platform includes the following steps:

[0060] S1. Press the safety buckle 12 on the ground to open the main boom 16 and rotating boom 17, so that the bolt 18 is engaged in the annular locking groove 19, and ensure the stability of the three sets of main booms and rotating booms 17.

[0061] S2. Test the power frequency signal generator 1 and the multi-rotor UAV on the ground using the controller;

[0062] S3. Operate the multi-rotor drone to carry the device to the vicinity of the wire using a lanyard;

[0063] S4. Operate the multi-rotor drone, hang the main arm 16 and the rotating arm 17 on the wire, lower the height of the multi-rotor drone, and make the carbon tube 8 fully contact the wire.

[0070] 3) The controller can be a handheld terminal. Using this invention, the voltage detection results can be fed back to the handheld terminal in real time, thereby solving the problem that ground personnel cannot accurately receive the sound and light signals when the overhead wires are too high.
